我们设计并建造了一个实验装置，我们称之为“热电桥”。其主要目的是同时测量相对Peltier系数和Seebeck系数。使用该装置，两个系数的系统误差是相等的，并且不需要在测量一个系数和另一个系数之间进行处理。因此，该装置特别适合于验证开尔文勋爵所假定的它们之间的线性关系。文中还介绍了导热系数的同步测量方法。样品由镍-铂对组成，在−20-60 °C的范围内进行测量，建立每个系数与温度的关系，随机误差几乎相等±0.2%，系统误差估计为−0.5%。由这些结果在此范围内验证了上述开尔文关系，证明了行为偏差为≤0.3%，包含在误差传播引起的不确定度±0.5%内。
We have designed and built an experimental device, which we called a ‘‘thermoelectric bridge.’’ Its primary purpose is simultaneous measurement of the relative Peltier and Seebeck coefficients. The systematic errors for both coefficients are equal with this device and manipulation is not necessary between the measurement of one coefficient and the other. Thus, this device is especially suitable for verifying their linear relation postulated by Lord Kelvin. Also, simultaneous measurement of thermal conductivity is described in the text. A sample is made up of the couple nickel‐platinum, taking measurements in the range of −20–60 °C and establishing the dependence of each coefficient with temperature, with nearly equal random errors ±0.2%, and systematic errors estimated at −0.5%. The aforementioned Kelvin relation is verified in this range from these results, proving that the behavioral deviations are ≤0.3% contained in the uncertainty ±0.5% caused by the propagation of errors.
